  • The study of the lining layer abrasing wear in the semi

    From the end of the twentieth century semi-autogenous grinding (SAG) of ores is the most progressive technology of ore preparation in world practice. As of 2010, in the world mining industry, about 200 large mills of full or partial SAG were in operation, including about 100 of them working in the iron oreAUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT ,Semi-autogenous grinding also relies on a relatively small Batch testing, process simulation, and a pilot plant were conducted on a magnetic taconite iron-ore in 2005. Compared with SAG mill grinding, autogenous grinding using feed prepared to include coarse, competent rock and
